To all whom it may concern: v

Belt-known that I, 'ERNEST"GOLDBERGER,

-a citizen ofthe United States of America,

residing at Detroit, inithe-county of Wayne. and State of Michigan, .havezinventedcertain new and useful Improvements in Disk Clutches, of which the following is-aspecification, reference beinghad therein to the accompanying drawings.

The inventionrelates to clutches of the disktype, and it isthe object of theinvention to obtain a simpleand compactco'n struction as hereinafterset forth.

In the'drawings:

Figure 1 is a central longitudinal-section Fig. 2 is a sectionalend elevation thereof. A and B are the drive and driven shafts in axial alinement' with each other. C is a housing member mounted upon the drive shaft A and provided with a key D for transmitting the torque thereto. The outer peripheral flange E of this housing is provided on its inner face with a series of keyways F for engagement wlth one set of the disks. G is a head member mounted upon I the driven shaft, B, being rotatively secured thereto by the key H. A hub portion of this head is provided with the annular'recess I in which is located a spring J. K is a cooperating head or clamping member, which is sleeved upon the shaft B and is provided with a grooved collar L for engagement with a pedal or other operating device.

is an annular frame mounted upon the head G through the medium of posts N, which pass through apertures O in the member K,

and is secured by the bolts P. These posts N' are arranged close to the outer face of the hub of'the member G and pass through the central opening in the disks Q, which engage the key-ways F. R are pins slidably engaging hearings in the annular member M and also passing through apertures in the members K and G. The inner ends of these pins are secured to a spring abutment member vS by cotterpins T, or other suitable means. U are driven disks which alternate with the disks Q, but are of smaller external diameter, so as to clearthe flange E and keyways F. These disks U are cut away for the passage of the posts N, but have portions V intermediate these posts which extend inward and-are apertured for engagement with the pins R.

With the construction as described, when Specification of Letters'latent.

,springJ upon the member-S will place a tension upon the pins R, which having a shouldered engagement R with the member K willcommuni'cate the pressure to the latter member. This will cause theclamping of the-whole series of .disks :between :the

.head G and the-member -K. .To release the clutch, the member K, is. moved. outward through: the medium ofgthezgrooved collar L and operating the pedal (not shown), ;this i movement being transmitted by the-compression of the spring J :In addition to the function of rformingfa conneetion between and M, which are rotatively fixed in relation to each other, communicate the torque to the driven shaft B. I

One of the principal advantages of the construction is the simplicity and compactness, which is largely due to the performance r Patented July 5,1921.

of the double function by the pins R. Thus, 7

the forming of key-ways upon the memberG is dispensed with and no additional clearance is required for the passage of. the con-- npction between the spring'and the clamping p ate. f 1

What I claim as my invention is:

1. The combination with the rotary drive and driven members in axial alinement, of a head secured to one of saidmembers having a recess in the hub portion thereof, a spring in said recess, a spring abutment member, a series of pins passing through said head connected at one end to said spring abutment, aclampingplate or head connected to said pins, and alternate drive and driven disks between said head and clamping plate, one set of disks being in engagement with said pins for the transmission of torque therethrough to said head.

. 2. In a disk clutch, the combination with rotary drive and driven members in axial alinement, of a housing secured'to one, of said members, a head secured to the other of said members within said housing forming one abutment for the series of disks,

tures in said fixed head, a springabutment attached to the inner ends of said pins, a spring within the recess of the hub bearlng against said spring abutment and the shoule der at the end of the recess, a series of alternately arranged drive and driven disks between said clamping head and fixed head, one set of disks being rotatively fixedto said housing and the other set of disks/aprojecting inward and being apertured for engagement with said pins, and means for moving said clamping headaway from said fixed head, said pins forming connections between said clamping head and the spring and also constituting torque members for connecting oneset of disks to said head.

3. In 'a disk clutch, the combination, with drive and drivenmembers in axial alinement, of a housing secured to the one and a fixed head secured to the other within said housing, said fixed head having a recessed hub, a clamping head having a collar surrounding the shaft for actuating said head longitudinally, an annular fume surrounding said collar and provided with a plurality of posts passing through apertures in said clamping head and secured to said fixed head, a series of pins passing through bearings in said annular frame, said clamping head and fixed head, said pins having a shouldered engagement with said clamping head, a spring in the recess in said hub, a spring abutment connected with said pins, and a series of alternately arranged drive and driven disks between said fixed head and clamping head, one set of disks being in engagement with said housing and the other set having inwardly projecting portions apertured for engagement with said pins, whereby said pins constitute torque connections for said disks and also connections between said spring and clamping plate.

4. The combination with rotary drive and driven members in axial alinement, of a head secured to one of said members, a spring abutting at one end against said head, an abutment member for the other end of said spring, a series of pins passing through said head connected at one end to said abutment member, a clamping plate or head connected to said pins, and alternate drive and driven disks. between said head and clamping plate, one set of said disks being in engagement with said pins for the transmission of a torque therethrough to said head;

In testimony whereof I aflix my signature.
